Schneider Electric GUTOR OP2130 Cooling Fan Monitoring & Control Board
Schneider Electric GUTOR OP2130 Fan Monitoring Board is a dedicated auxiliary protection module specifically engineered for Gutor PEW, PDW, and SDC industrial-grade uninterruptible power supplies (UPS) and high-power rectifiers.
Because heavy industrial power conversion equipment generates significant thermal loads, continuous forced-air cooling is non-negotiable. The OP2130 acts as a continuous watchdog, monitoring the speed, current draw, and operational integrity of the cabinet’s internal cooling fan arrays to prevent catastrophic thermal runaway.

Unique Product Description
The GUTOR OP2130 serves as the primary thermal safety layer on the system’s internal auxiliary bus. In heavy industries like chemical processing or marine environments, cooling fans are exposed to harsh elements—such as ambient soot, salt air, and abrasive dust—which can cause bearing degradation or total fan seizure.
The OP2130 continuously tracks the physical rotation speeds or current draws of the cooling fan network. If a fan begins to slow down due to mechanical wear, or drops out entirely, the board isolates the fault and instantly alerts the primary system controller. By providing early stage warnings before internal heat sinks reach critical temperatures, it allows operators to schedule targeted fan replacements without the UPS having to force an emergency trip to static bypass.
Product Advantages and Features
Predictive Thermal Protection: Catches micro-drops in fan RPM or unusual current spikes, preventing unexpected overheating in high-load thyristor or IGBT inverter blocks.
Optically Isolated Signaling: Onboard optocouplers isolate the core logic channels from inductive voltage kickbacks or electrical noise originating from the fan motors.
Resilient Conformal Coating: Circuit board traces are completely sealed to prevent short-circuits or trace erosion caused by moisture, salt mist, or airborne chemical gases.
Fail-Safe Alarm Relays: Designed with hardwired alarm states that automatically drop to a closed warning position if the board loses its own logic power supply.
Related Models & Same-Series Variations
The OP2130 integrates directly with Gutor’s primary internal diagnostics, safety routing, and control layers:
GUTOR OP2130: (Current Standard) Dedicated cooling fan monitoring module.
GUTOR OP6280: Basic Signal Board (aggregates various minor system warnings and auxiliary contact loops).
GUTOR OP6281A: Logic Signal Interface Board (handles higher-priority hardware safety interlocking loops and trip matrices).
GUTOR OP2456 / OP2456B: Main Control CPU Boards (the central processing units that receive and act upon fan failure alerts routed from the OP2130).
Application Cases
Oil, Gas, and LNG Facilities: Installed in outdoor unconditioned modular equipment shelters (e-houses) where constant cooling air is required to maintain safe internal thyristor temperatures.
Offshore Drilling Platforms: Integrated into marine-hardened UPS enclosures where high coastal humidity and vibration accelerate mechanical wear on cooling fan bearings.
Power Plants and Substations: Deployed within safety-critical backup control systems to guarantee that auxiliary ventilation circuits are fully operational before high-capacity battery charging cycles begin.
Installation and Maintenance
Static-Safe (ESD) Mandate: This card utilizes low-voltage communication ICs and sensitive diagnostic paths. Field technicians must wear an active, grounded ESD wrist strap during handling and installation.
Safe Isolation Control: While Gutor systems are built with high reliability, the fan monitoring board should only be unseated or replaced when its specific control rack partition is entirely de-energized or when the system is safely operating on isolated maintenance bypass.
Retention Clip Verification: When connecting multi-pin ribbon cables or modular wire terminals to the board face, ensure all lock mechanisms are firmly engaged to prevent terminal resistance errors caused by site-wide equipment vibrations.
